Web 2.0 Summed Up
This video pretty much summarizes the Web 2.0 phenomenon:
Note that, aside from being of very high quality, it also has all of the elements of a viral video- it’s already got a good deal of views, and expect those views to explode in the days to come.
Oh and yes, I’ve become quite a bit more cynical about Web 2.0 over the past few months. If you want a powerful reality check, go work 14 hour days at a Web 2.0 startup for a few months 
I think the biggest problem with Web 2.0 is that most of these companies focus on changing the world/revolutionizing the industry, and not enough time focusing on running a business, which, at least in theory, even a Web 2.0 Internet startup is.
Imagine if someone asked you for a million dollars to start a small department store that doesn’t sell anything or produce any revenue, and whose business plan is to get bought by Wal-Mart.
Add a 2.0 and put it on the Internet, and you’ve got a promising startup.
